DEVELOPMENT OF A COMPREHENSIVE ONLINE CATALOGUE OF AVAILABLE OFFICIAL CHARTS.

1. DEVELOPMENT OF A COMPREHENSIVE ONLINE CATALOGUE OF AVAILABLE OFFICIAL CHARTS. WEND Stakeholders Meeting September 2006 Anthony Pharaoh - IHB

2. Requirement to Determine ENC Coverage 6th WEND COMMITTEE MEETING Norfolk, Va, USA, 18-19 May 2001 “Germany recommended that IHB produce a catalogue that accurately shows the actual coverage and availability of ENC data for the shipping community”. IHB issued CL 67/2002 asking “…..Member States are requested to provide the information below for every ENC cell already produced, under production or planned” • ENC Cell name • Navigational purpose code, • Cell limits • S-57 Edition, i.e. 3.0 or 3.1; • Date of production; • Date of issuance, i.e. when the ENC cell is on the market; • Website and/or e-mail address where further details on the cell and information on how to obtain the data can be found.

3. Responses from CL 67/2002 IHB Developed a static catalogue – available on the IHO web site. CL 67/2002 • Presented to the: • 7th WEND Meeting (Lima, Peru, May 2003) • 15th CHRIS Meeting (IHB, June 2003) • Norway offered to assist the IHB in developing an interactive web catalogue

4. IHO ENC Catalogue Thematic criteria were to establish what ENCs were; - planned or in production (red) - released but not yet commercially available (blue) - commercially available (black) Administrative interface developed to enable MS and RENCS to login and update the system.

5. IHO ENC Catalogue – Administrative Interface

6. Requirement for a new Catalogue IMO/IHO Corresponding Group (CG) • NAV50 established a CG • CG endorsed a proposal from IHO to develop an online catalogue. • NAV51 endorsed this proposal • NAV51 prepared a draft specification • NAV51 re-established the CG and tasked it to review the draft specification.

7. Focus and Scope of the New WEB Catalogue • Focus • Only those ENCs that areavailable for use. (i.e. on the shelf). • Scope • The new catalogue need to show; • ENC coverage • RNCs coverage for those areas where no ENC coverage exists • A list of “adequate backup” paper charts.

8. Lessons Learned from Previous Catalogue Development • Requirement for ENC data limits – not just cell limit • Need to keep a historical record of coverage evolution. • Need to improve the mechanism for acquiring coverage and metadata information (harvesting tools). • Need for more detailed metadata • Need to be standards based – interoperability • Need to develop mechanisms to keep the catalogue current • As far as possible, take account of the needs of stakeholders (RENCs, Data Servers/VARs, Distributors and OEMs). • Need to make a coverage (dataset) and metadata resource available for use by all stakeholders.

9. Sources of Coverage Information and Metadata RENC 1 RENC 2HOs ENC HO 1 HO 2 HO 3 RNC Maritime Authorities and HOs “adequate backup” paper charts

10. Types of Information Required Coverage Information Metadata Information Identifier(ENC Cell name - RNC/Chart number) Issuing authority(possibly on behalf of another Member State) Producer Authority Standard format(e.g. S-57 Edition 3.1, BSB,HCRF) Distribution Method(e.g. issuing HO, RENC, free download) Allowance of SENC distribution: Yes/No Compilation scale / usage band Co-ordinates of edges Edition date RNC ENC

11. Metadata Resources IHO S-100 Discovery Metadata Profile Update Information

12. Coverage Information Metadata <extent> <EX_GeographicBoundingBox> <westBoundLongitude>-127.46</westBoundLongitude> <eastBoundLongitude>-122.48</eastBoundLongitude> <southBoundLatitude>43.71</southBoundLatitude> <northBoundLatitude>49.73</northBoundLatitude> </EX_GeographicBoundingBox> <EX_BoundingPolygon> <polygon> -123.45, 43.71 -123.00, 46.23 -123.00, 48.35 -123.22, 49.23 -123.45, 49.73</polygon> </EX_BoundingPolygon> </extent> <extension base="double"> <attribute name=“metadata" type=URI “http://www.responsibleRENC.com#sw33492.mta" use="required"/> </extension>

13. Coverage Data Files • The ENC and RNC Coverage Files; • will be used to generate ENC and RNC coverage limits in the new catalogue • should be made available on the IHO web site in a standard format for all stakeholders to use • should be regularly maintained through the issue of updates, and new editions • all historical versions of coverage data files should be kept.

16. Summary of Key Components • Needs the cooperation of RENCs HOs and MSA to ensure coverage and metadata information is kept current. • As far as possible the generation of coverage and metadata information should be automated as output from a database or using harvesting tools. • It should take into account the needs of Distributors, VARs, OEMs and other stakeholders. • Should be standards based – ensure interoperability.
